Quantification of thermotolerant Campylobacter in Swiss water treatment plants, by real-time quantitative polymerase chain reaction


Rinsoz, T; Hilfiker, S; Oppliger, A (2009). Quantification of thermotolerant Campylobacter in Swiss water treatment plants, by real-time quantitative polymerase chain reaction. Water environment research, 81(9):929-933.

Abstract

A total of 49 wastewater samples from 23 different wastewater treatment plants (WWTPs) were analyzed using real-time quantitative polymerase chain reaction for the presence and quantity of thermotolerant campylobacters. Thermotolerant campylobacters were detected in 87.5% (21/24) and 64% (16/25) of untreated and treated wastewater samples, respectively. Their concentration was sufficiently high to be quantified in 20.4% (10/49) of the samples. In these samples, the concentration ranged from 68,000 to 2,292,000 cells/L in untreated wastewater and from 10,800 to 28,000 cells/L in treated water. We conclude that thermotolerant campylobacters present a health hazard for workers at WWTPs in Switzerland.
